The content backend Gatsby deserves
Most CMSes give you a content API and call it done. Sanity is the structured content backend for Gatsby teams that need more than pages and blog posts. Model your business in code, give editors a better workspace, and deliver content to your Gatsby site, other channels, and AI-powered experiences from one source of truth.
Why Gatsby developers choose Sanity
Schema as code
Your content model lives in code, not in a rigid admin UI. Define document types, references, validation, and editorial structure in your Studio config, then evolve it as your Gatsby project grows.
Flexible querying
Use the official Gatsby source plugin to pull Sanity content into Gatsby’s GraphQL layer, or use @sanity/client directly when you want GROQ for custom app logic. You are not boxed into one access pattern.
Type safety
typegen can generate TypeScript definitions from your schema and GROQ queries, which makes Gatsby integrations easier to maintain as your content model changes.
Editorial customization
Fully programmable editorial UI, so you can ship content tools your team actually wants to use without maintaining a separate app.
Power anything
When your content is data, stored as JSON, you can power web, mobile, storefronts, internal tools, and agentic applications from the same backend.
Built for structured content, not page fields
Gatsby is great at turning data into fast websites. The hard part is usually upstream. Most CMSes still push teams toward page-shaped content, duplicated fields, and brittle editorial processes.
Sanity takes a different approach. Content is stored as structured JSON in the Content Lake, then queried and assembled for the experience you want to build. That makes reuse easier, keeps your model cleaner, and gives you a foundation that can outgrow a single Gatsby site.

FAQs
Yes. Sanity works well as a headless CMS for Gatsby because it gives you structured content, a customizable editing environment, and multiple ways to query content. You can use the official Gatsby source plugin to pull Sanity content into Gatsby's GraphQL data layer, or use @sanity/client directly when you want to query with GROQ.
Most teams connect Gatsby to Sanity with the official Gatsby source plugin. It pulls content from Sanity into Gatsby so you can query it during builds using Gatsby GraphQL. If you need more control, you can also connect directly with @sanity/client and fetch content from Sanity outside Gatsby's source layer.
Yes. Gatsby can use Sanity content through the official Gatsby source plugin, which makes that content available in Gatsby's GraphQL layer. Sanity also supports deploying its own GraphQL API from your schema if you want a Sanity-hosted GraphQL endpoint.
Yes. Gatsby developers often use the source plugin for build-time GraphQL queries, but Sanity also supports querying content directly with GROQ through @sanity/client. That is useful when you want more flexible query logic or need to fetch exactly the shape of data your app needs.
Yes, with some nuance. Sanity TypeGen can generate TypeScript definitions from your schema and GROQ queries, which helps when you want stronger typing in your Gatsby integration. Sanity currently documents TypeGen as an experimental feature, so teams using GraphQL heavily may still prefer established GraphQL typing tools in that part of the stack.
No. You can use Sanity as the CMS for a Gatsby site, then reuse the same structured content across other frontends, apps, and services later. That means Gatsby does not have to be a dead end. The same content model can support your website today and other channels as your stack grows. You can see more in the JavaScript client documentation.
Yes. Sanity's primary query language is GROQ, but it also supports deployed GraphQL APIs generated from your schema. Sanity's docs are clear that GROQ is the main querying model, while GraphQL is available for teams that want that API shape or ecosystem tooling.
Traditional CMSes often force content into page-shaped fields and rigid editorial workflows. Sanity gives Gatsby teams structured content, schema as code, and a customizable Studio so developers can model content around the product they are building, not around CMS limitations. That makes it easier to reuse content, scale the model over time, and support more than one frontend from the same backend.
